  • Recommended Electric Trailer Jack For A 2018 Jayco Whitehawk
    Hi Tom, I have two options to replace the electric tongue jack on your Jayco Whitehawk: Option 1: Electric Jack w/ Footplate # EJ-3520-BBX. This jack is going to be your no-frills 'get the job done' style jack. It has a 3,500lb capacity and what it lacks in looks it makes up for in dependability. The simple design of this jack also allows for easier replacement of damaged or worn components unlike a lot of other jacks that require complete replacement when something malfunctions. Option...

  • Powered Trailer Jack and Winch Recommendations for an Enclosed Car Hauler Trailer
    Thanks for reaching out and on your new trailer, Eric! The Lippert Smart Jack # LC643589 is great in theory, but they've had issues with water leaking into the head, and I haven't recommended one since I found out that they don't cover that under warranty and their solution is to replace the jack entirely. For a high-performance jack it's hard not to nod at the Ultra-Fab Phoenix # UF38-944040 because it's the fastest operating jack that we carry, and it uses a ball screw which is a very...

  • Troubleshooting Phoenix 4000 Electric Jack Not Working
    Phoenix Electric Trailer Jack - A-Frame - 22-1/2" Lift - 4,000 lbs # UF38-944040 sounds like it needs a better ground connection. You can wire it directly to the battery like in the installed video or you can install the ground wired to the trailer frame directly with a bare metal to metal connection. The battery itself may need a charge so I'd check that out as well by connecting to a different battery or charging the trailer battery then reconnecting the jack. If the red LED flashes...

  • Troubleshooting Phoenix Electric Trailer Jack UF38-944040 Beeps And Will Not Go Down
    Hello Clint, thanks for getting in touch. With the Phoenix Electric Trailer Jack # UF38-944040, generally when the unit beeps and does not function properly, it is due to a low voltage situation. The first thing to do will be to check your battery and make sure it is fully charged and in good working order. Also make sure the jack is properly grounded. Check the jack wiring for any damaged or frayed wire that may be causing a short. If this does not resolve the problem we could be looking...

  • Recommended Nice A-Frame Jack For Heavy Car Hauler
    Hi Aaron; so there isn't anything that can be used with a cordless impact gun, that's just not something that is attainable. But for a strong, fast, heavy-duty A-frame jack that can handle the weight you need? That we can do with the Phoenix jack: - Phoenix Electric Trailer Jack # UF38-944040 This has a 4,000 lb lift capacity which is more than enough for your 7,000 lb car hauler trailer to use in the manner you described. It also extends 6 inches in just under 10 seconds which I know...

  • Mounting Flange Diameter of Phoenix Electric Trailer Jack
    Hey Byron, thanks for writing in, and the mounting flange is 5.3" (or 5-5/16") on the Phoenix Electric Trailer Jack # UF38-944040. You made an awesome choice here with the Phoenix as it's as good as it gets for an A-frame jack. The thing cooks in regards to travel (at least relative to trailer jacks), extending 6" in 9-1/2 seconds. I also thought you might want the rest of the dimensions so I went ahead and got ahold of the manufacturer to get all the dimensions of the Phoenix # UF38-944040.

  • Troubleshooting Ultra-Fab Electric Jack Has no Power When Lifting Trailer
    It sounds like you're saying it is hooked up to power but it doesn't have the ability to raise the trailer. This could be the batteries or a problem with the wiring. It is probably getting power, it just may not be enough to lift the trailer. I would start by checking the wire running to the jack using a circuit tester like # PTW2993. You could also double check the trailer batteries. If you find it has 12V power and still isn't working it may be that the motor is giving out. It would...

  • Troubleshooting Ultra-Fab Phoenix Electric Tongue Jack That Won't Extend or Retract
    The Ultra-Fab Phoenix Electric Trailer Jack with Remote- 5,500 lbs # UF38-944055 or 4,000 lb # UF38-944040 without remote sounds like it may have a mechanical issue. I recommend using the manual crank to extend or lower the jack. If you can use this, then you isolate the issue to electrical with a possible bad ground or motor issue. If you can't physically move the jack with the manual crank then we know the issue is mechanical with the inner rod seized or having stripped threads. If...

  • Electric Tongue Jack Upgrade Recommendation for a Safari Condo Alto F2114
    Thanks for reaching out, Ger! For a simple replacement A-Frame jack I recommend checking out the Electric Jack w/ Footplate and 7-Way Plug # EJ-3527-BBX which is essentially your industry-standard quality jack with a 7-Way plug that you'll connect to your vehicle to operate the jack. If you want something that operates a bit quicker then I recommend the Phoenix Electric Trailer Jack # UF38-944040 instead because it lifted 1,000 lbs in a quarter of the time (10 seconds) that it took the...

  • Recommended Electric Tongue Jack 2017 Keystone Passport Ultra Lite Grand Touring Travel Trailer
    Hello Scott, so we have quite a few electric jacks that will be of sufficient capacity for your 2017 Keystone Passport Ultra Lite Grand Touring Travel Trailer. If you are looking for the fastest-moving jack, I recommend the Phoenix Electric Trailer Jack # UF38-944040. This has a 4,000 lb capacity and it will move 6" in about 10 seconds under 1,000 lbs of tongue weight. I imagine that with your camper being 7,500 lbs loaded, your tongue weight should be pretty close to 1,000 lbs so you should...

  • Recommended Fast Electric A-Frame Jack for 12K Trailer
    The Phoenix Electric Trailer Jack part # UF38-944040 will be an excellent option for a 12,000 lb trailer as it only needs to cover the max tongue weight which at 15% would only be around 1,800 lbs. This is one of the fastest jacks on the market with up to 10" of travel in 18 seconds. It also has an industry leading 10-year warranty.

  • Recommended Heavier Duty Upgrade For FIC 3500 Electric A-Frame Trailer Jack
    Electric A-frame trailer jacks often have the same bolt pattern, yes. Just keep in mind that a higher-capacity jack doesn't necessarily mean more speed, it's all about the jack itself. For example, the 3,500 lb Ultra-Fab Electric A-Frame Jack # UF38-944017 extends 6" in 25.3 seconds (with 1,000 lbs of tongue weight), while the 4,000 lb Bulldog Trailer Jack # BD500200 extends 6" in 28.5 seconds (with 1,000 lbs of tongue weight). That said, since you mentioned wanting a heavier-duty jack,...

    For an A-Frame jack replacement on your 2020 Grand Design Reflection 300RBTS I recommend the Phoenix Electric Trailer Jack # UF38-944040. I'm not sure what your current jack capacity is but this has a lift capacity of 4,000 lbs, which is more than enough for your travel trailer. It has a 10-1/2" retracted bracket height and a 28-1/2" extended height with a total travel of 22-1/2". This also comes with a 10-year warranty if registered within 90 days that can't be beat.

  • Electric Jack, Battery, Lighting, and Solar Power Info for 2022 Featherlite Car Trailer
    The etrailer Electric Jack part # EJ-3520-BBX would be a solid option for an electric jack for your 2022 Featherlite Car Trailer. It's a solid, standard powered jack, but if you wanted a really quick jack that goes up and down incredibly quickly you'd want the Phoenix Electric Trailer Jack part # UF38-944040. For a battery that would work great a deep cycle is a solid option like the Bright Way Deep Cycle part # BRW57FR which is a 155 ah battery. For wiring 10 gauge wire like part # 10-1-1...

  • Can I Use the Phoenix 4000 Jack With Lippert Ground Control TT Auto-Level System
    If you're wanting to continue to use the Electric Ground Control TT Automatic 5-Point Travel Trailer Leveling System # LC672136 then you need to replace your tongue jack with the exact replacement part # LC421366. While I do love the Phoenix Electric Trailer Jack # UF38-944040, since it only has power and ground connections you will get error messages and everything will be all jacked up if you mix it with the leveling system (pun intended). The Lippert replacement jack has connectors...

  • Can The Phoenix Electric Trailer Jack Be Wired To The 7-Way Instead Of The Battery
    You could power the Phoenix Electric Trailer Jack # UF38-944040 by wiring it to the 12v accessory wire of the 7-way in your junction box, like part # 38656, instead of wiring it directly to the battery. There are pros and cons to this though. The pros being that the wiring is a bit more tucked away and less likely to corrode on terminal in the junction box versus sitting outside with the battery (if you don't have a cover). You'll also never have to worry about a dead battery since you'll...

  • Options if an Ultra-Fab Phoenix Electric Trailer Jack Has a Bad Circuit Board
    Good news and bad news. There is not a replacement circuit board available for the Phoenix Electric Trailer Jack # UF38-944040. So if the circuit board goes bad, it will either need to be covered under warranty or you'll need a new jack. The good news is that the Phoenix Electric Trailer Jack # UF38-944040 comes with a 2 year warranty or all the way up to a 10 year warranty if you registered your jack within 90 days of purchase.

  • Best Solution For Gaining Tail Gate Clearance On A-Frame Trailer Tongue Jack
    Since the Ultra-Fab Electric A-Frame Jack # UF97FR has a triangular bolt pattern it would rotate the jack 120 degrees and may or may not work for your application. There are other jacks which have multiple mounting patterns on the flange like the Phoenix # UF38-944040 which will allow for 90 degree placement on the jack. A much simpler option I find is to use an extended Ball Mount # BH20 or a extended Drop Shank # EQ90-02-4600 if you have a weight distribution hitch. This means no mater...

  • Does Phoenix Electric A-Frame Trailer Jack Have Auto Retract
    The Phoenix Electric Trailer Jack # UF38-944040 retracts with the simple push of a button, so if that is what you meant by "auto retract function" then yes, it certainly does. These buttons are also how it extends, and the accompanying photo shows exactly where these buttons are located on the front of the jack. The Phoenix has a 4,000 lb capacity, offers 22-1/2" of total travel and is an easy bolt-on installation. It is also possible you were referring to something like the Lippert...

    You should never use an impact drill to raise or lower a jack since it would hammer as it drills and most likely damaged the internal components of the jack making it harder to manually raise and lower it. Ultra-Fab has stated that the Phoenix Electric Trailer Jack # UF38-944040 isn't the easiest jack on the market to manually raise and lower, but what you're describing is well beyond the norm. When manually overriding the jack you need to first unscrew the fuse and remove it and then...
